As far as I know, no, it's not possible. You either loop one pattern, or play the song from start to finish.

It would be DAMN useful if you could set up it to loop, say, 4 patterns, instead of just 1. It's a bit awkward to create 64-step patterns for example, it'd be easier if you could have 4 16-step patterns and just loop all of those.

2. you can jump to any Patterm ( 1-99) by tapping the respective pattern number at the top of the Sequencer Pattern Map. You can do this whilst the song is playing. -

- Hence - when you reach bar 90 - you cna jump back to Bar 10 ( for example) but you have to be quick!
You can do this whilst the song is playing. - also use the A and Y buttons to skip to next Pattern or jump back to previous pattern - Play it Live !!!
3. Build in 'Breathing space' break patterns that give you a bit of time to jump
